    The methods of layer-by-layer interference phase scanning with digital holographic reproduction of azimuth and ellipticity polarization maps for differential diagnosis of benign (nodular goiter - NG) and malignant (papillary thyroid - PT) thyroid tumours are presented. All studies in representative groups of histological sections M and AC were conducted using a circular laser beam. This ensured the azimuthal invariance and repeatability of measurements of polarization maps NG and PT. Integrated, and layer-by-layer polarization maps of NG and PT were received. Values of statistical moments of 1st - 4th order, which characterize NG and PT samples coordinate distributions of azimuth and ellipticity polarization have been determined and systematized. A set of statistical parameters - diagnostic markers most sensitive to changes in the polycrystalline structure NG and PT has been determined. The results of information analysis - determination of accuracy of vector-parametric and polarization-interference methods of differentiation of benign and malignant thyroid tumours are presented.

    Our work uses a polarization matrix formalism to analyze and algorithmically represent optical anisotropy by open dehydration of blood plasma films. Analytical relations for Jones matrix reconstruction of optical birefringence maps of protein crystal networks of dehydrated biofluid films are found. A technique for 3D step-by-step measurement of the distributions of the elements of the Jones matrix or Jones matrix images (JMI) of the optically birefringent structure of blood plasma films (BPF) has been created. Correlation between JMI maps and corresponding birefringence images of dehydrated BPF and saliva films (SF) obtained from donors and prostate cancer patients was determined. Within the framework of statistical analysis of layer-by-layer optical birefringence maps, the parameters most sensitive to pathological changes in the structure of dehydrated films were found to be the central statistical moments of the 1st to 4th orders. We physically substantiated and experimentally determined the sensitivity of the method of 3D polarization scanning technique of BPF and SF preparations in the diagnosis of endometriosis of uterine tissue.
